SPRING-ACTUATED FAN.

Application filed April 12, 1915.

To all w hom t may concern.'

Beit known that* I, HENRY GABEL, a citizen ofthe United States of America, residing at New York, inthe county of New York and State of New York, have invented new and useful Improvements in Spring-Actuated Fans, 4of which the following is a specification. u v

This invention relates to improvements in portable fans, of the power driven type and particularly tothat class which derive power from a spring motor combined in the supporting structure.

The objects of the invention are, first, to Iprovide a fan which will run at a high rate of speed for a great length of time uninterruptedly from 'a single winding of the motor, and which can be stopped or started at will.

A second object is to provide means, combined with the structure, which cause the fan `to oscillate automatically so as to ldeliver a blast of air in constantly changing directions within the scope of its capacity.

A lthird object is 'to provide a readily portable fan that may be placed and operated in any convenient location without making special provision for it.

These, and other `objects that will become apparent, are attained by the novel construction and combination of parts hereinafter described and shown in the accompany-ing drawings, forming part of this specification, and in which Figure 1 is a 'partial side elevation and vertical sectional view showing an embodiment of the invention, the section being taken substantially on line 1 1 of Fig. 2, Fig. 2 is a transverse sectional view, taken on line 2 2 of Fig. 1. Fig. 3 is a similar sectional view, taken on line 8 8 of Fig. 1. Fig. 4 is a fragmental sectional view showing the upper rear corner of the structure casing and the oscillating means therein. Fig. 5 is an enlarged fragmental perspective view of the oscillating means. Fig. 6 is a Vcross sectional view taken on line 6 6 of Fig. 1. Fig. 7 is an enlarged sideelevation and section showing the spindle thrust and Specification of Letters Patent.

radial bearings, and motor spring center. Fig. 8 is a transverse sectional view taken on line 8 8 of Fig. 1', and'Fig. A9 is a view showing a double radial bearing used in the structure.

The base 510 of the structure is a hollow casting provided with feet I11 upon which it rests on its foundation; it has a central hub 12 in which is fitted a hardened bushing 14 held in place by the cap 15 and screws `16. The upper edge of the base is lianged outwardly and bored to receive a cover plate 17 from this cover rise four standards 18 uniformly spaced, and extending to the top where their ends are radially bent inward and connected by the plate 19. Surrounding these standards is a cylindrical casing 20, the outturned flange 21 of which is screwed to the plate 17 and a tight top cover 22 is provided to exclude dust.

Above the bearing or sleeve 14 in the hub 12 is a similar sleeve 24 held in the hub 25,'

secured to the plate 17; in the sleeve 24 is vroller bearing 2G and in alinement with it, in the sleeve 14 is a similar bearing 27, these bearings supporting the vertical shaft 28, the weight and thrust of which is 'taken on the 'glass yplate 29 resting on the 'cap 15. Between these roller bearings the shaft 28 has enlarged portions 30, flattened on one side and carrying the hook 81 to which one end of the motor spring 32 is attached, the other end being secured to the interior of the hollow base 10 by the screw 33.

To the end ofthe shaft 28 extending through the bearing 26 is firmly secured the worm wheel 85 carrying on its upper side the ratchet wheel 3G and driven by the worm 37 rotatable in bearings 38 and 39 secured on the .plate 17 in such manner as to allow the worm to be meshed or unmeshed with the worm wheel at will. Motion is communicated to the worm 37 'by means of the manually operated crank '40. The worm wheel is prevented -from rotating in a reverse direction when winding by means of the pawl 41 and spring 42, both of which are carried by a disk 43 having on its upper side the actuating arms 44. rThus means are provided for winding the spring and transmitting its action to mechanism hereafter described.

The upper end of the shaft 28 is bored to receive a ball 46 upon which rests the lower end of a. stationary spindle 47, which enters the shaft sufficiently to be guided laterally thereby the shaft being further provided with a support 48, rigid with the plate 19 and extending up to the apex of the cover 22 through which the spindle slightly protrudes.

In order to provide a proper high rate'of speed to the fan, a plurality of speed 1ncreasing devices are used, three being shown all of which are substantially alike and of the planetary type of gearing.

Inwardly extending lugs 50 are formed Y with the standards 18 and to them are secured toothed rings or'bevel gears 51, the teeth being uppermost and engaging with bevel pinions 52 secured on short shafts 53 having at their pointed opposite inner ends bevel gears 54. These shafts are revoluble in bearings 55, provided with thrust collars 56, and are mounted on plates 57 rotatable about the spindles 47 on the special seven point, double ball bearings 58, the sleeve 59 of which is fast to the plate 57.

lThe action of the motor spring, when the worm wheel is released is to transmit rotary motion through the ratchet 36 and pawl 41 to the plate 43, causing the arms 44 to press against the edge of the lowermost plate 57, turning around the axial spindle 47 5 this turning motion causes the pinion 52 to revolve, by reason of its being in mesh with the stationary or fixed gear 51, rotating with it the bevel gear 54 at a speed in proportion to the number of teeth on the pinion and fixed gear respectively,

Meshing with the bevel gear 54 is a bevel pinion 60 freely rotatable on the spindle 47,

provided with thrust collars 61, and carrying arms 44 engageable with the next higher plate 57, where the same speed accelerating effect is obtained in an intensified manner; this continues through each of the gear trains until the uppermost, where the last pinion 60 is formed with a sleeve 63 carrying the gear 64, meshing with the pinion fast on the shaft 66 which extends through its bearing 67 and a slot in the casing 2O and has mounted on it the fan 70.

Inv order to hold the fan quiescent when desired the gear 64 has a plurality of holes in its web receptive of the point of the thumb screw 68 the head of which extends above the cover 22, the screw being threaded into a portion of the support 48. Thus it will be seen that the fan 70 can be revolved at a high rate of speed or held still as may be desired.

' The fan shaft bearing 67 is carried on an larm 72 pivotally supported on the spindle 53, as it is revolved radially around the in- Y ner circumference of the casing, coming in contact with the projection 79, formed with the traveler, and carried by it until the traveler entersthe straight, out-turned end 80, of the slot 77 moving the projection 79 out of Contact with the shaft end, allowing the end to pass, whereupon the traveler moves slowly back into its initial position Vby'reason of the re-action of the fan blades against the air, the shaft 53 meanwhile, continuing its circuit within the casing until it again engages with the projection 79 for a succeeding cycle of operation.

From the foregoing, it will be seen that as the cable is drawn by the traveler, the fan shaft is caused to move in one direction, and when the traveler is released, the fan shaft moves back by the action of the f an blades, thus causing the fan to oscillate on the axis of the spindle 47 and that it will continue to do so as long as the fan mechanism is operated.V Y

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: Y

The combination in a portable fan, a spring motor, a disk driven thereby, a plurality of speed increasing units arranged interconnectedly one above Ythe other, the lower being driven by said disk, a transversely mounted fan driven by the uppermost of said units, means for constantly changing the axial direction of rotation of said fan, said means being operated in one direction by the movement of said units, and in the other direction by the reaction of the fan, and a locking means whereby said fan may be prevented from operation.
